Sealing detection device

Abstract

The utility model relates to the technical field of maintenance tools, in particular to a sealing detection device which comprises an air pipe, an air inlet connector and a pressure gauge. The air inlet connector is communicated with the air pipe, and the pressure gauge is connected to the air pipe and used for detecting the air pressure in the air pipe. When sealing detection is carried out, an operator enables the air pipe to be communicated with the fluid channel of the to-be-detected element. And then the air inlet connector is communicated with compressed air serving as an air source. The pressure gauge detects air pressure in the air pipe in real time. An operator firstly determines whether the to-be-detected element generates an execution action, and if the to-be-detected element cannot generate the execution action, the to-be-detected element is damaged or leaks seriously. If the execution action can be generated, the pressure gauge is observed, and if the reading of the pressure gauge is not changed or the change range is very small, the sealing performance of the to-be-detected element is good; and if the reading of the pressure gauge is greatly reduced or fluctuates severely, the sealing performance of the to-be-detected element is poor, so that the sealing performance of the to-be-detected element can be more accurately detected.

Description

Technical Field

[0001] The present application relates to the technical field of maintenance tools, and more specifically, to a sealing detection device. Background Art

[0002] At present, the proportion of automatic transmission models in the field of passenger cars in my country is increasing, exceeding 70%. At the same time, due to the changes in various automatic transmission technologies, the design life of the transmission has been shortened and the failure rate has been high to a certain extent, so the automatic transmission maintenance market is extremely hot. In medium and large automatic transmission maintenance companies, the equipment and special tools can be said to be relatively complete, but in some small professional maintenance plants, 4S stores and comprehensive maintenance companies, the hardware facilities are still not very complete. For the automatic transmission maintenance business, some are handed over to professional factories, and some are still repaired by themselves. In the actual maintenance process, the return rate is also relatively high. The main reason is that the sealing test of various automatic transmission terminal components is unreliable, and the traditional "compressed air test" method is still used. The specific method is to pass compressed air into the fluid passage of the component to be tested, and judge whether the component to be tested is leaking by whether the compressed air can drive the component to be tested to perform an action. This detection can only find out whether the component performs the action correctly, and cannot accurately test the sealing of the component to be tested. When the component to be tested leaks slightly, the compressed air can still drive the component to be tested to perform an action, and the credibility of the tested sealing result is not high. Utility Model Content

[0003] In order to overcome the problems existing in the related art to a certain extent, the purpose of the present application is to provide a sealing detection device, which can solve the problem of inaccurate sealing results when the traditional "compressed air test" method is used to detect the sealing of the component to be tested. The preferred technical solutions among the many technical solutions provided in the present application can produce many technical effects as described below.

[0004] The present application provides a sealing detection device, comprising:

[0005] An air pipe, used for communicating with a fluid passage of the component to be tested;

[0006] An air inlet connector, connected to the air pipe, and used to connect to an air source;

[0007] A pressure gauge is connected to the trachea, and the pressure gauge is used to detect the air pressure in the trachea.

[0008] Optionally, it also includes:

[0009] A test connector is connected to the air pipe and is used to be connected to the fluid passage of the component to be tested. A conical surface is arranged on the outer side of the test connector.

[0010] Optionally, the test joint is made of rubber.

[0011] Optionally, it also includes:

[0012] An air valve, wherein the air inlet connector is connected to the air pipe via the air valve.

[0013] Optionally, the air valve is a roller-type mechanical valve.

[0014] Optionally, it also includes:

[0015] A first handle is provided with an air passage running through the first handle, the air inlet connector is communicated with a first end of the air passage, and a second end of the air passage is connected with the trachea.

[0016] Optionally, it also includes:

[0017] A second handle is connected to the side wall of the trachea.

[0018] Optionally, the first handle and the second handle are respectively arranged on both sides of the trachea.

[0019] Optionally, it also includes:

[0020] A pressure regulating valve, the air inlet connector is connected to the air pipe through the pressure regulating valve.

[0021] The technical solution provided by this application may have the following beneficial effects:

[0022] The present application provides a sealing detection device, comprising: an air pipe, an air inlet connector and a pressure gauge. The air pipe is used to communicate with the fluid passage of the component to be tested. The air inlet connector is connected to the air pipe, and the air inlet connector is used to connect the gas source. The pressure gauge is connected to the air pipe, and the pressure gauge is used to detect the air pressure in the air pipe. When a component needs to be sealed, the operator connects the air pipe with the fluid passage of the component to be tested. Then the air inlet connector is connected to the compressed gas as the gas source. At this time, the compressed gas enters the air pipe from the air inlet connector and then passes into the fluid passage of the component to be tested. At this time, the pressure gauge detects the air pressure in the air pipe in real time. The operator first determines whether the component to be tested generates an execution action. If the execution action cannot be generated, the component to be tested is damaged or leaks seriously. If the execution action can be generated, then observe the pressure gauge. If the reading of the pressure gauge does not change or the range of variation is very small, the sealing of the component to be tested is good; if the reading of the pressure gauge is greatly reduced or fluctuates violently, the sealing of the component to be tested is poor, so that the sealing of the component to be tested can be detected more accurately.

[0023] It should be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0029] The following is an explanation of the embodiments with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the contents of the utility model described in the claims. In addition, the entire contents of the structures represented by the following embodiments are not limited to the solutions required as the utility model described in the claims.

[0030] refer to Figure 1 The present embodiment provides a sealing detection device, comprising: an air pipe 1, an air inlet connector 2 and a pressure gauge 3. The air pipe 1 comprises a connecting pipe 11 and a three-way pipe 12, the pressure gauge 3 is connected to a first air port of the three-way pipe 12, the air inlet connector 2 is connected to a second air port of the three-way pipe 12, and a first end of the connecting pipe 11 is connected to a third air port of the three-way pipe 12.

[0031] When a sealing test is required for a component, the operator connects the first end of the connecting tube 11 to the fluid passage of the component to be tested. Then the air inlet connector 2 is connected to the compressed gas as the gas source. At this time, the compressed gas enters the air pipe 1 from the air inlet connector 2, and then enters the fluid passage of the component to be tested. At this time, the pressure gauge 3 detects the air pressure in the air pipe 1 in real time.

[0032] The operator first determines whether the component to be tested has an execution action. If it cannot, the component to be tested is damaged or leaking seriously. If it can, observe the pressure gauge 3. If the reading of the pressure gauge 3 remains unchanged or the variation range is very small, the sealing of the component to be tested is good; if the reading of the pressure gauge 3 drops significantly or fluctuates violently, the sealing of the component to be tested is poor, so that the sealing of the component to be tested can be detected more accurately. Moreover, by observing the pressure gauge 3, the air pressure of the compressed gas can be controlled to prevent the damage of the component to be tested caused by excessive air pressure.

[0033] As an optional embodiment, it also includes: a test connector 4, the test connector 4 is connected to the second end of the connecting tube 11, and a conical surface is provided on the outer side of the test connector 4. When performing a sealing test on the component to be tested, the conical surface on the outer side of the test connector 4 is pressed against the interface of the fluid passage of the component to be tested, so that the sealing performance between the test connector 4 and the fluid passage of the component to be tested is better, and serious leakage between the test connector 4 and the fluid passage of the component to be tested is prevented, which has a significant impact on the test result.

[0034] In some embodiments, the test connector 4 is made of rubber material, so that the sealing performance between the test connector 4 and the fluid passage of the device to be tested is better.

[0035] As an optional embodiment, it further includes: an air valve 5, wherein the air valve 5 can be a roller-type mechanical valve. The air outlet of the air valve 5 is connected to the second air port of the three-way pipe 12. The air inlet connector 2 is connected to the air inlet of the air valve 5. When the compressed gas enters from the air inlet connector 2, if the air valve 5 is in an open state, the compressed gas can enter the air pipe 1 through the air valve 5; if the air valve 5 is in a closed state, the compressed gas is blocked by the air valve 5 and cannot enter the air pipe 1.

[0036] In this way, after the air valve 5 is closed, the air inlet connector 2 can be kept connected to the air source. When a component needs to be tested for sealing, the operator connects the first end of the connecting tube 11 to the fluid path of the component to be tested, and then opens the air valve 5. The compressed gas can enter the fluid path of the component to be tested after entering the air pipe 1 to test the air tightness of the component to be tested. After the test is completed, the air valve 5 can be closed again.

[0037] As an optional embodiment, it further includes: a first handle 6. An air passage is provided in the first handle 6 along the length direction. The first handle 6 is connected to the air inlet connector 2 so that the air inlet connector 2 is communicated with the first end of the air passage. The first handle 6 is connected to the three-way pipe 12 of the trachea 1 so that the second end of the air passage is communicated with the trachea 1. Thus, the compressed air entering the air inlet connector 2 can flow through the air passage in the first handle 6 and enter the trachea 1.

[0038] When a sealing test is required for a component, the operator can hold the first handle 6 and press the test connector 4 connected to the air pipe 1 onto the fluid passage interface of the component to be tested, which makes it more convenient to apply force.

[0039] As an optional embodiment, it further includes: a second handle 7. The second handle 7 is connected to the side wall of the air pipe 1. When a sealing test is required for a certain component, the operator can hold the second handle 7 and press the test connector 4 connected to the air pipe 1 against the fluid passage interface of the component to be tested, which makes it more convenient to apply force.

[0040] In some embodiments, the first handle 6 and the second handle 7 are both connected to the side wall of the trachea 1. The first handle 6 and the second handle 7 are respectively located on both sides of the trachea 1. The operator can hold the first handle 6 and the second handle 7 with both hands, respectively, and apply force on both sides of the trachea 1, which makes the force application more uniform and effective.

[0041] As an optional implementation, it also includes:

[0042] The pressure regulating valve 8, the air inlet connector 2 is connected to the air pipe 1 through the pressure regulating valve 8.
